Abstract (en)
[origin: EP0796808A1] The pipe distributor has a housing with three pipe connections, and a connecting cock with two flow channels. A pipe intake (3) in the housing is connected to one of the pipe outlets (4,5) in the housing via a flexible pre-curved spiral hose (2). The hose connects all three pipe connections (3-5), and has a slide (6) with support bracket (10). A seal carrier has a guide arm (7) to generate a 360 degrees movement of the hose. A gas pressure spring engages on the part of the hose connected to the pipe intake, while its other end supports itself on the turnable slide.
